Pt/Y0.16Zr0.84O1.92/Pt thin film solid oxide fuel cells: Electrode microstructure and stability considerations

▶ Systematic insights on performance variation reported in literature. ▶ A power density of 1037 mW cm−2 at 500 °C was obtained in a μSOFC using 5% H2. ▶ A maximum power density of 95 mW cm−2 at 440 °C was achieved using 5% CH4. ▶ Power density was found to reduce by 50% at 400 °C after 12 h of testing.
